I have an LG WH14NS40 Blu-ray burner which has worked well for a number of years on multiple computers (I've replaced the computers but kept the drive, switching it to each new one). I have used IMGBurn to burn DVDs and Blu-rays for years now, with very few problems. I use the automatic verify option of IMGBurn, which automatically cycles the tray then verifies the disc that has just been burned. It usually works correctly.
However, I decided to burn some DVDs last night, and ran into problems. The first one burned and verified without incident. The second one seemingly burned without incident, but when the tray finished cycling, BD-Rebuilder was taking forever to verify it. The verification was at a rate of about 50 kbps, and it was estimating that it would take about 36 hours to finish. Meanwhile, the burner was making a pitiful noise like it was straining to try to read information off of the disc. I canceled the verification.
I've had this problem a few times before, but it was always just a once-off that would happen once every few months or so. So I assumed that this would again be the case. I then tried burning the disc again (to a different blank disc), and it burned and verified without incident. But the next disc that I burned ran into the same verification problem. I tried burning to another disc, and the problem hit again.
I ejected the last disc that gave me an error and put it back in to try to verify it with IMGBurn again, and the same problem continued. But I then closed IMGBurn, ejected the disc and put it back in yet again, then reopened IMGBurn and selected its verify option, and was able to successfully verify the disc against the ISO I had burned it from in just a few minutes. (I still don't trust the disc, though.)
This error striking three times in one night has me extremely worried. Does anyone know what could be causing this problem or what I should do about it?
